Add a burst of life to your boring, bare walls with Eazy Wallz ($120 and up). These large-scale, DIY wall murals install in just minutes, and are available in any size you want. You can choose from the company's large library of images or upload your own, and as an added bonus for apartment-dwellers, they can be removed and reused countless times, which means no explaining to the landlord why there's now a life-sized portrait of He-Man in the bathroom.
